Question

Which answers I should have to answer

Answer 1

Given:

The table of point scored in 5 games.

After game 6, the mean number of points scored per game is 9.

To find:

The points scored by Maya in game 6.

Solution:

Let x be the points scored by Maya in game 6. Then sum of scores in all 6 games is:

`Sum=8+12+10+6+14+x`

`Sum=50+x`

We know that, the formula for mean is:

`\text{Mean}=\frac{\text{Sum of all observations}}{\text{Total number of observations}}`

So, the mean number of points scored per game is:

`\text{Mean}=(50+x)/(6)`

It is given that the mean number of points scored per game is 9.

`(50+x)/(6)=9`

`50+x=9* 6`

`x=54-50`

`x=4`

Therefore, the correct option is A.
